Linear Technology LTC3215 Datasheet
The LTC3215 is a low‑noise, high‑current charge‑pump DC/DC converter designed to drive LEDs up to 700 mA from a 2.9 V to 4.4 V input. It features three boost modes (1x, 1.5x, 2x), automatic mode switching, ultralow dropout current source, and a tiny 3 mm × 3 mm 10‑lead DFN package.
The datasheet provides electrical characteristics, pin descriptions, operation details, thermal protection, soft‑start behavior, and recommended component selections for low noise and stable operation. Typical applications include camera flash, torch lights, and general LED lighting.
